MORGAN BURNS, OF HYDE PARK, ILLINOIS, ASSIGNOR OF ONE-HALF OF HIS RIGHTTO OS\VELL A.

BOGUE, OF SAME PLACE.

DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 230,918, dated August10, 1880. Application filed May 10, 1880. (No model.)

To all whom ct may concern:

Be it known that I, IVIORGAN BURNS, of Hyde Park, in the county of (lookand State of Illinois, have invented certain new and useful Improvementsin Dumping-(Jars; and I do be ai'ull,clear, and exact description of theinvention, that will enable others skilled in the art to which itappertains to construct and make use of the same, reference being had tothe accompanying drawings, and to letters and figures of referencemarked thereon, forming a part of this specification.

This invention relates to that class of cars so constructed as to permitof the car-body being tilted for the purpose of discharging the loadthrough either side of the car, the eX- act arrangement and operation ofwhich will be hereinafter more fully described in detail, and set forthin the claim.

Figure 1 is a side elevation; Fig. 2, an end view of the same; and Fig.3 is an end view, partially in section, showing the position of the carwhen tilted for the purpose of discharging the load.

Referring to the drawings, A represents the body or box of the car; B,the supporting frame-work, and O the wheels, this form of constructionbeing common to this class of cars, my improvements relating especiallyto certain devices or mechanism for holding the car-box in a horizontalplane and securing the hinged sides of the car-box in such a manner asto readily and conveniently permit of the car-box being tilted, in themanner shown in Fig.3 of the drawings, sidewise in either direotion,when unloading the same.

The rockers 4 are attached to the under side of the car-box A, and reston the rocker-beds 5, which are provided with the vertical projectingposts 6, which fit into corresponding recesses in the rockers 4.,serving to retain these parts in the proper position.

The side or sides 7 of the car ward from the bottom, as shown in Fig. 3of the drawings, through the medium of the hinges 8, the upper ends ofwhich are atswing outtached to the bracing-rod 9, and from thence,extending downward, are bolted to the swinging sides of the car, asshown in Fig. 1 of the drawings.

The lever 10 is pivoted to the swinging sides, moves in the guard 11,and is provided with the locking-latch 12, which is adapted to engagewith the bracket 13, thereby securing the swinging sides of the car in alocked position.

The check-chains 14 are for the purpose of preventing the car fromtilting beyond a certain point, and the chains 15 serve to retain theequilibrium of the car when loaded and moving.

At one end of the car is placed the rod 16, moving in a horizontalplane, the ends having a bearing under the corner of the car, as shownin Fig. 2 of the drawings.

The vertical operating-lever 17 is pivoted to the rod 16 at 18, itslower end forming the fulcrum-bearing 19. The coiled springs 20 are forthe purpose of returning the rod 16 to its normal position.

The standards 21 support the rod 16 to 'its bearings on the under sideof the car, the lower ends of which are turned at right angles relativeto the vertical part, and bolted to the frame-work in a horizontalplane, as shown in Fig. 2 of the drawings.

In practical use, when the car is to be dumped the latch securing theswinging side of the car should be released. Then move the lever 17 inthe proper direction for releasing one end of the rod 16 from itssupporting position on the under side of the'car. The opposite end ofthe rod 16 remaining in a supporting position prevents the car frombeing tilted in the wrong direction.

When the load is discharged and the car returned to a horizontalposition the supporting rod 16 is automatically thrown into a lockingposition by means of the springs 20.

This arrangement presents a simple, durable, and convenient device foroperatingdumping-cars.

The locking devices cannot be released by the motion or vibration of thecar. Thus all snpporting-standards 21, all constructed, ardanger ofaccidentally dumping the car is ranged, and operating in the manner andfor avoided. the purpose setlforth.

Having thus described my invention, What his 5 I. claim, and desire tosecure by Letters Pat- MORGAN BURNS.
